Patented Apr. 18, 1933 UNITED STATES PATENT OFFICE EDWIN J. MCIL'VRIED,OF CLEVELAND, OHIO, ASSIGNOR, BY ASSIGNMENTS, TO WESTERN ELECTRICCOMPANY, INCORPORATED, OF NEW YORK, N. Y., A. CORPORA" TION OF NEW YORKApplication filed April 24,

The present invention relates to the art of wire drawing andparticularly to attachments for wire drawing machines, whereby theefliciency and productivity of these ma chin-es may be increased.

In the use of the usual or ordinary type of wire drawing machines, it isfrequently necessary to change the machine from one in which the wire isreceived upon spools to one in which the wire is laid up in open coils.In changing from spooling to coiling, it has been necessary to makeextensive alterations in the-delivery end ofthe wire drawing machine,which requires considerable time, and labor, and it is the purpose ofthe present invention to make the "operation of chan ing over moreconvenient and expeditious.

The present invention provides for a new and novel arrangement of thedelivery end of a wire drawing machine, whereby the op-v erator canchange and adapt the machine for I either operation in a comparativelyshort period and without necessitating the extended shut down of themachine. The invention is shown and described in its preferred form andin which form it can be changed over rapidly and economically.

While the description and drawings are detailed so as to enable theinvention to be readily understood by those skilled in the art, it willbe appreciated that changes and -modifications may be made thereinwithin the scope of the invention as set out in the claims.

In the drawlngs there IS shown a w1re drawing machine provided with thespooling and coiling apparatus, the machine being shown somewhatdiagrammatically, as the details of the drawing machine are no part ofthe present invention, except as the same may be used in conjunction andcombination with the improvement.

' Figure 1 is a plan view of a wire drawing machine, as adapted for thespooling operation, showing the manner in which the'invention is to beapplied thereto.

Figure ,2 is a section in the line 2-2 of Figure 1 along the capstan.shaft showing the machine equipped forspooling.

Figure 3 is a similar section showing the.

machine equipped for the coiling operation, showing the capstan removedand the block in place in the machine.

The wire drawing machine is indicated by the numeral 1. The main or wormshaft of the wire drawing machine is indicated by the numeral 2, bybeing driven from the motor 3. In addition to driving the drawing rolls,this shaft extends "through the machine and through suitable cliltchesand gearing and drives the spool shaft 5 and the spool 6 thereon.

The shaft 2, is provided'with the worm 8 which drives the worm gear 9 onthe transverse shaft 10 mounted in the bearings 11 on the machinehousing 12. The shaft 10 extends through the housing to provide adriving extension 15. on which is keyed and removably mounted the mainor finishing capstan 16.

In spooling the wire the capstan 16 is mounted on the shaft 10 beingheld in posit1 on by the nut 18. The wire is. given the requisite numberof turns about the capstan and is then passed to the spool 6.

To change over to the coiling method, the

upper part of the housing is provided with an opening 20, circular inform, and covered, when not in use by removable plate 21. When the coveris removed a ring 22 is placed over the opening 20, being properlylocated by means of a flange or rib 23, and held inposiassembled, tomesh with the bevel driving pinion 36 on the shaft 10. When the capstan$3 is removed 1t may be replaced by a collar The operation andadvantages of the aption by bolts 24 which also pass throughthe paratuswill be readily appreciated. The

' change-over from the spooling to the coiling operation is madepossible by removing the capstan 16, and the plate 21, and placing theblock assembly in the opening 20,- with the bevel gear 34 in mesh withthe bevel gear 36. The change-over is made without disturbing the pathof the wire, the receiving point in the block being coincident with thepoint at which the wire passes on to the capstan.

What is claimed is: 1. In a strand working machine, means to rovideinterchangeable finished strand deivery means and finished strandtake-up means comprising ahousing, a drive shaft therein, a capstanadapted to be mounted on the shaft for delivering the finished strand,and a winding unit adapted to be driven by the shaft and to be removablymounted on,

the housing as a unit,-with the strand receiving point of the windingunit substantially coincident with the strand receiving point of thecapstan and with the plane of rotation of the winding unit substantiallyperpendicular to .the plane of rotation of the capstan.

2. In a wire drawing machine, means to provide interchangeable finishedwlre delivery means and finished wire take-up means comprising ahousing, a drive shaft 1' ournaled therein, a capstan adapted to bemounted on the shaft for delivering the finished wire, a drive gear onthe shaft, said'finished, wire take-up means removable as a unit andcom-' prising a secondary housing, a driven shaft j ournaled in thesecondary housing, a gear on the driven shaft, and a drum for laying upthe Wire in coil form mounted on the driven shaft within the secondaryhousing, said secondary housing adapted to be mounted on said firstnamed housing with the gear on said driven shaft meshing with the .drivegear on the first named shaft and with the periphery of the drumsubstantially coincident with the wire receiving point of the capstan.

3. In a strand working mechanism, interchangeable strand delivery meansand strand laying-up means comprising a housing hav-- ing an aperturetherein, a shaft extending within said housing, a capstan adapted to bemounted on the shaft external tosaid housing for deliverin the finishedstrand, a transmission mem er secured to said shaft, said strand layingup means comprising a stationary member adapted to be secured to saidhousing, a rotatable drum, a second shaft secured to said drum andextending through said stationary member, another transmission membersecured to said second shaft and adapted to slidably engage said firstmentioned transmisison member, an located between said stationary me berand said second shaft for preventing movement between said stationarymember and said second shaft in a direction parallel to said shaft andpermitting rotatable movement between means said stationary member andsaid second shaft,

and said strand laying-up means positioned over and adapted to cover theaperture in said housing with the periphery of the drum substantiallycoincident-with the strand re ture therein, a shaft extending withinsaid housing, a capstan adapted to be mounted on the shaft external tosaid housing for delivering the finished strand, a transmission membersecured to said shaft, said strand laying up means comprising astationary casing, a
